Description

Heat exchange plate of battery
Technical Field
The present invention claims priority from french application 1910397 filed on 2019, month 9 and day 20, the contents of which (text, drawings and claims) are incorporated herein by reference.
The present invention relates to the field of batteries, more particularly to the field of electrically driven batteries for hybrid or electrically driven vehicles.
Background
Throughout this document, "battery" is understood to include a combination of at least one battery module comprising at least one electrochemical cell. The battery optionally includes electrical or electronic components to manage the electrical energy of the at least one module. When present, the plurality of modules are combined in a slot or housing, typically denoted in english as "pack batteries", and thereby form a battery pack, which housing typically includes a mounting interface and coupling terminals.
In addition, throughout the present document, the term "electrochemical cell" is understood to mean a cell of the lithium ion (or Li-ion) type, Ni-Mh type or Ni-Cd or lead type, for example, which generates an electric current by a chemical reaction.
In this field, it is known to assemble the heat exchange plates of the battery in a battery well, and then to fit the battery module in said well against the cooling plate.
A cooling plate for such a configuration is known from patent document FR-a1-3003938, which has a heat exchange plate comprising a base made of molded plastic material and contact plates made of heat transfer material. The base made of plastic material allows a greater variety of fixing means with the support to which it is fixed, for example by adding specific fixing tabs.
A disadvantage of this design is that the plate and the module are fixed independently of each other in the housing, which results in a dispersion of positioning between the module and the plate. Moreover, the housing with the assembly interface for assembling the modules and the plates is complicated to manufacture and even more complicated when the housing is typically a large part for receiving a plurality of modules and a plurality of heat exchanger plates.
Disclosure of Invention
The object of the present invention is to overcome these drawbacks, in particular by optimising said cooling plate.
To this end, the present invention is directed to a heat exchange system including a battery module and a heat exchange plate heat-exchanged with the battery module by conduction, the heat exchange plate including a base plate and a heat contact plate contacting and fixed with the battery module, the base plate including a first fixing member for fixing the heat exchange plate on a support, and including a second fixing member for fixing the heat exchange plate against the battery module, the second fixing member being separated (distint) from the first fixing member.
Thereby, the base plates can be preassembled on the battery module, thereby being accurately positioned with respect to each other due to the reduced dimensional chain. Also, when the base plate is integrated with the first fixing member and the second fixing member, since only the mounting interface for mounting the base plate is included and the mounting interface for mounting the battery module is no longer included, the support for receiving the base plate may be regarded as simplified.
According to an embodiment of the invention, the substrate is made of a plastic material.
Thus, the substrate may have a greater thickness and thus greater shape stiffness, and not be too heavy, compared to a metal substrate such as an aluminum alloy. This shape rigidity thus enables a plurality of battery modules to be fixed on the same substrate.
Moreover, still in contrast to metallic materials, the plastic material is thermally insulating. For example, the substrate is made of a thermally insulating plastic material having a thermal conductivity (λ) of less than 2W.m-1.K-1 at 20 ℃. This makes it possible in particular to avoid heat exchanges between the substrate and the environment outside the heat exchange system.
According to an embodiment of the invention, said plastic material comprises a filler (charge).
It is noted that, as an example, a plastic material in the form of a resin is filled with glass or carbon fibres, the thermal conductivity of the material thus formed being slightly higher than that of the unfilled plastic, between 0.15 and 2w.m-1.K-1 at 20 ℃, depending on whether the fibres are oriented and on the direction of heat propagation considered, which makes it possible to increase the rigidity of the substrate and therefore the size of the substrate.
According to an embodiment of the invention, the first or second fixing part comprises a metal insert inserted in the material of the base plate, the metal insert having an aperture shaped for receiving a screw.
The first fixing part comprises, for example, a screw and an insert forming a sleeve with a central smooth aperture crossed by the screw. The fastening force of the screw is thus taken up by the sleeve and not by the base plate, the threaded end of the screw engaging in the threaded hole of the support. Creep (creep) of the plastic material is thereby avoided.
The second fixing means comprise, for example, a screw with a threaded central aperture crossed by a threaded end of the screw, and an insert, the head of which locks the battery module against the heat exchange plate without risk of damaging the threads of the insert (when this insert is metallic).
According to an embodiment of the invention, the base plate and the thermal contact plate form a cavity between each other through which a cooling fluid flows.
According to an embodiment of the invention, the substrate comprises, in its thickness, a groove through which the cooling fluid flows, the cavity forming a first passage location for the cooling fluid and the groove forming a second passage location for the cooling fluid.
These positions or stages are superposed on each other in the thickness of the heat exchange plate. The path of the coolant fluid in the cavity depends on the region of the battery module to be cooled, and may be, for example, straight in a plurality of parallel ducts, or in the form of coils (serpentines) arranged in a shingled arrangement (imbriqus) or not. The path of the cooling fluid in the grooves does not depend on thermal stresses (since the substrate is made of a thermally insulating material), but on the desired (usually minimized) fluid load losses.
Thereby, the second pass position is capable of isothermally transporting the coolant fluid.
The groove can also increase the shape rigidity of the substrate without increasing the weight of the substrate.
According to an embodiment of the invention, the first location and the second location are fluidly connected in series.
The second position thus forms a fluid return circuit which, by being thermally insulated, does not interfere with the efficiency of the heat exchange generated between the battery module and the heat exchange plate. The coolant fluid at the first location is completely drained from the second location.
According to an embodiment variant of the invention, the first location and the second location are fluidically connected in parallel.
The second position thus forms a circuit for transporting a portion of the coolant fluid that, being thermally insulated, is not re-heated by the fluid in the cavity. Which second location opens, for example, into a cavity and/or a groove of the second heat exchanger plate.
The invention also aims to provide a battery comprising a heat exchange system as defined above and a casing for confining (confining) the heat exchange system, the support being the bottom of the casing.
The housing for example comprises a container for receiving the heat exchange system, which container is covered with a cover. The housing thus forms a confined inner space for protecting the combination of the module and the heat exchanger plates from any water splash or impact.
The invention also aims to provide an assembly method for assembling a battery as defined above, which method comprises successively a first assembly step for assembling the heat exchange plate against the battery module and a second assembly step for assembling the assembly on the bottom of the casing.
The invention also aims to provide a vehicle comprising a battery as described above.
Drawings
Other features and advantages of the present invention will become more apparent from the following detailed description of the invention, when read in conjunction with the accompanying drawings, in which:
figure 1 shows a heat exchange system according to the invention.
Fig. 2 shows the heat exchange system, with a sectional view at the second fixing part.
Detailed Description
FIG. 1 illustrates a heat exchange system according to a non-limiting embodiment of the present invention. The heat exchange system includes ten battery modules 2 and a single heat exchange plate 1 that exchanges heat with each of the battery modules 2 by conduction. The battery modules 2 are distributed in a group of eight modules 2 and in a group of two modules 2, in a variant not shown, there are two hot plates 2 of different sizes, one in thermal contact with each of the modules of the group of eight modules 2 and the other in thermal contact with each of the modules of the group of two modules 2. Of course, other configurations are possible, i.e. with three or more plates, and with modules 2 of any form.
The modules 2 are preferably parallelepipedic and have a face in contact with the heat exchanger plates 1. In the example of fig. 1, this face is the lower face of the module 2 when the module 2 is in the position of use, for example in a land vehicle, but in a variant, this face may also be any face of the module 2.
Between the contact surface and the hot plate 1, a heat-conducting paste or pad 12 (see fig. 2) is generally interposed, which facilitates the exchange between the module 2 and the plate 1 by conduction by filling up irregularities or voids, which are generated by manufacturing variations of the module 2 or the plate 1.
The exchange between the module 2 and the plate 1 by conduction is via a heat flow considered in two possible directions: the heat directed from the module 2 towards the plate 1 is used to cool the module 2; or conversely, the heat from the plate 1 towards the module 2 is used to heat the module 2.
A network of coolant fluid pipes (not shown) couples the plates 1 to each other, the coolant fluid conveying heat towards an exchanger (not shown), such as an air/coolant fluid exchanger.
In a variant, the cooling fluid is replaced by a gas or a phase-change fluid.
Figure 2 shows a heat exchanger plate 1 in thermal contact with a face of a module 2. The plate 1 comprises a base plate 3 and a thermal contact plate 4 in contact with the battery module 2, which is fixed to the base plate 3, for example by crimping or gluing or screwing. The base plate 3 comprises first fixing means 6 for fixing the heat exchanger plate 1 to a support (not shown). The base plate 3 includes a second fixing member 7 for fixing the heat exchange plate 1 against the battery module 2. The second fixing part 7 is separate from the first fixing part 6.
The base plate 3 is made of a plastic material, for example of injection-molded plastic. In a variant, the plastic material comprises a filler.
The first fixing part 6 or the second fixing part 7 comprises metal inserts 10, 8 inserted in the material of the base plate 3, which metal inserts 10, 8 have apertures shaped for receiving screws (not shown). In the example shown, the insert 10 of the first fixing member 6 (the so-called first insert 10) is a sleeve with a central smooth aperture crossed by a first screw, the threaded end of which engages in the threaded hole of the support, each end of the sleeve being flush with the outer surface of the base plate 3, so that the sleeve assumes the full fastening force between the head of the first screw and the support. The insert 8 of the second fixing member 7, the so-called second insert 8, has a threaded central aperture which engages with a threaded end of a second screw passing through a smooth aperture 14 of the module 2, the head of said second screw fastening the battery module 2 against the heat exchange plate 1 without risk of damaging the threads of the second insert 8 (when this second insert is metallic).
The first insert 10 and the second insert 8 are for example overmoulded by the base plate 3. In a variant, these inserts 10, 8 are screwed, glued or crimped in the base plate 3.
It is noted that the first and second inserts 10, 8 are arranged in the thickness of the ribs 13 of the base plate 3 to facilitate the adhesion between the inserts 10, 8 and the base plate 3. Ideally, the ribs 13 are disposed partially or completely along the length of one of the four sides of the base plate 3 (ideally on the longest side) to further stiffen the base plate 3. In the example shown, only one single first rib 13 is visible, but it is understood that a second rib 13 is arranged on the opposite side of the base plate 3 and parallel to said first rib, which second rib 13 also integrates the first and second fixing parts 6, 7. Other geometries of the ribs 13 and of the base plate 3 are conceivable, in particular when the battery module 2 is not parallelepiped, but for example cylindrical or has a fracture plane (planes) in order to adapt to the interface of the vehicle structure.
According to the embodiment shown on fig. 2, the base plate 3 and the thermal contact plate 4 form between each other a cavity 5 through which the cooling fluid flows. Moreover, the substrate 3 comprises, in its thickness, a groove 11 crossed by said cooling fluid, the cavity 5 forming a first passage position of said cooling fluid and the groove 11 forming a second passage position of said cooling fluid.
The first and second locations are fluidly connected, for example, in series, but in a variation, the first and second locations are fluidly connected in parallel.
These positions or levels are superposed on each other in the thickness of the heat exchanger plate 1. The path of the coolant fluid in the cavity 5 depends on the area of the battery module 2 to be cooled, and the paths 16, 17 may be straight, for example in a plurality of parallel ducts 16, 17, or have the form of labyrinths (labyrinths) or coils, arranged with or without imbrication. As a general way of routing, these ducts 16, 17 shown in fig. 2 are formed, for example, by a diaphragm 15 resulting from the moulding of the base plate 3 and being implemented against the thermal contact plate 4.
The path of the cooling fluid in the grooves 11 does not depend on thermal stresses (since the substrate 3 is made of a thermally insulating material), but on the desired (usually minimized) fluid load losses. The example of fig. 2 shows this path, which extends in the groove 11, in a similar manner to this same partition 15.
Note that, advantageously, this partition 15 participates in the rigidity of the base plate 3 in the same manner as the ribs 13.
The in-line connection of the two locations is for example effected by fluid communication (not shown) with the ends of the heat exchanger plates 1 between the two locations. The connection may be internal or external to the heat exchanger plate 1 by using pipes in the network of coolant fluid pipes. The coolant fluid extends successively through the first location and then the second location, which thereby forms a fluid return circuit that, by virtue of being thermally insulated, does not interfere with the efficiency of the heat exchange that takes place between the battery module 2 and the heat exchanger plate 1. The coolant fluid at the first location is completely drained from the second location.
The parallel connection is implemented, for example, by arranging a cooling fluid inlet in the heat exchanger plate 1, which cooling fluid inlet is common to said two locations, each location having a cooling fluid outlet separate from the other. The fluid leaving said first location may thus be conducted towards the air/coolant fluid exchanger via the coolant fluid pipe network, while the fluid leaving said second location may be conducted towards the fluid inlet of the other heat exchanger plate 1 before it turns to be conducted towards said air/coolant fluid exchanger.
The second position thus forms a circuit for conducting a portion of the coolant fluid, which, being thermally insulated, is not reheated by the fluid located in the cavity 5. This second location opens into the cavity and/or groove of the second heat exchanger plate, for example via a network of coolant fluid conduits.
In a manner not shown, the casing confines the heat exchange system, the combination thus forming a battery (for example a vehicle traction battery). Said support is for example the bottom of the housing.
The housing insulates the module 2 from all contact with splashed water and limits all gas emissions of the module 2 to the inner space of the housing.
Vehicles, in particular electric or hybrid vehicles, advantageously comprise such a battery.
It is noted that the assembly method for assembling such a battery is advantageous and comprises, in succession, a first assembly step for assembling the heat exchange plate 1 against the battery module 2 and a second assembly step for assembling the assembly on the bottom of the casing. This method makes it possible to obtain a combination of module 2 and heat exchanger plate 1, which is pre-assembled, for example at the supplier, and is independent of the assembly of the combination in the assembly line of the vehicle in which the shell is integrated. This method facilitates the assembly while guaranteeing the quality of the assembly of the module 2 on the plate 1 in terms of relative positioning and thermal conductivity. The assembly line is less complex, the edges of the production line are less blocked and the floor space is reduced.
The first assembly step for assembling the heat exchange plate 1 against the battery module 2 is carried out by an operator or by an automated assembly means which carries out the first screwing sub-step by using second fixing means 7 which, in the example described above, comprise second screws for fastening the heat exchange plate 1 against the battery module 2. The second assembly step for assembling this combination on the bottom of the shell is carried out by an operator or by an automated assembly means which carries out the second screwing sub-step by using a first fixing means 6 which, in the example described above, comprises a first screw for fastening the heat exchange plate 1 against the bottom of the shell.
